RESUMO Obesidade leva ao acúmulo de gordura e disfunção do tecido adiposo. Compostos ativos foram descritos no óleo-resina de copaíba, que apresenta efeitos anti-inflamatórios, antimicrobiais e antioxidantes. Contudo, não há dados sobre os efeitos do óleo-resina de copaíba sobre o tecido adiposo. Assim, testamos a hipótese de que o óleo-resina de copaíba pode prevenir ou minimizar a obesidade, e inflamação e estresse oxidativo no tecido adiposo em resposta à dieta rica em sacarose. Ratos Wistar machos foram casualmente divididos para receber dieta padrão (C, n = 8), dieta padrão e 30% de sacarose na água de beber (S, n = 8), e dieta padrão e 30% de sacarose na água de beber + óleo-resina de copaíba (S+CO, n = 8). O óleo-resina de copaíba foi administrado via gavagem (200 mg kg-1 dia-1), por oito semanas. Animais dos grupos não suplementados (C e S) receberam veículo via gavagem, em volume equivalente ao oferecido ao grupo S+CO. Ao final do experimento, amostras de sangue e tecido adiposo epididimal foram coletadas para análises bioquímicas, inflamatórias e de estresse oxidativo. A suplementação com óleo-resina preveniu ganho de peso, adiposidade, resistência à insulina e aumento de IL-1β, inibiu parcialmente o aumento nos níveis de glicemia de jejum, lipídeos e níveis de IL-6 no tecido adiposo, além de melhorar o sistema de defesa antioxidante no tecido. Nossos resultados sugerem que o óleo-resina de copaíba pode ser usado como uma boa estratégia para a prevenção da obesidade e suas complicações.

ABSTRACT Obesogenic diets lead to fat accumulation and dysfunctional adipose tissue. Active compounds were described in copaiba oleoresin, which presents anti-inflammatory, antimicrobial, and antioxidant properties. However, there are no data regarding the effects of copaiba oleoresin in adipose tissue. Therefore, we tested the hypothesis that the copaiba oleoresin could prevent or minimize obesity and adipose tissue inflammation and oxidative stress in response to a high sucrose diet. Male Wistar rats were randomly assigned to receiving commercial chow (C, n = 8), commercial chow and 30% sucrose added to the drinking water (S, n = 8), or commercial chow and 30% sucrose added to the drinking water + copaiba oleoresin (S+CO, n = 8). Copaiba oleoresin was given at a dose of 200 mg kg-1 day-1 by gavage for eight weeks. C and S animals received vehicle, at equivalent volume, by gavage. At the end of the experiment, blood samples and epididymal adipose tissue were collected for biochemical, inflammatory, and oxidative stress analyses. Copaiba oleoresin supplementation prevented weight gain, adiposity, insulin resistance, and increased IL-1β levels. Additionally, copaiba oleoresin partially attenuated the increase in fasting glucose levels, lipids, and IL-6 levels, and improved the redox status in adipose tissue. Our results suggest that the use of copaiba oleoresin could be a good strategy for prevention of obesity and its complications.

Abstract Objective The aim of this study was to evaluate the use of vaginal molds, made with three-dimensional (3D) printing, for conservative treatment through vaginal dilation in patients with vaginal agenesis (VA). Methods A total of 16 patients with a diagnosis of VA (Mayer-Rokitansky-Küster-Hauser syndrome, total androgen insensitivity syndrome, and cervicovaginal agenesis) from the Federal University of São Paulo were selected. Device production was performed in a 3D printer, and the polymeric filament of the lactic polyacid (PLA) was used as raw material. A personalized treatment was proposed and developed for each patient. Results There were 14 patients who reached a final vaginal length of 6 cm or more. The initial total vaginal length (TVL) mean (SD) was 1.81(1.05) and the final TVL mean (SD) was 6.37 (0.94); the difference, analyzed as 95% confidence interval (95% CI) was 4.56 (5.27–3.84) and the effect size (95% CI) was 4.58 (2.88–6.28). Conclusion The 3D printing molds for vaginal dilation were successful in 87.5% of the patients. They did not present any major adverse effects and offered an economical, accessible, and reproducible strategy for the treatment of VA.

Abstract Background Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease that leads to muscle weakness and paralysis. Fatigue is a disabling symptom, frequently reported in ALS, but remains under-investigated in this population. Thus, an accurate investigation of this symptom and possible associated factors in this clinical condition is needed to assist in the establishment of an adequate treatment approach. Objective To investigate the presence of fatigue in individuals with ALS and possible factors correlated with this symptom. Methods Sixty-five individuals with sporadic ALS participated in the present study. Demographic, clinical, and functional aspects were investigated. Evaluations involved the Fatigue Severity Scale (FSS), ALS Functional Scale (ALSRFS-R), and Quality of Life (QoL) questionnaire (ALSAQ-40). Descriptive and correlation analyses were performed with SPSS statistical program for Windows version 19.0 (IBM Corp., Armonk, NY, USA). Results Among the 65 individuals evaluated, 44.6% (n = 29) presented fatigue based on the FSS. The mean fatigue intensity was 5.4 ± 1.2 and only 10.4% used a specific medication for fatigue. Differences between the groups with and without fatigue were found regarding sex (p = 0.049), pain intensity (p = 0.026), functioning (p = 0.004), disease severity (p = 0.029), and QoL (p = 0.000). Fatigue was correlated with pain intensity (r = 0.425; p = 0.001), muscle strength (r = - 0.356; p = 0.004), functioning (r = - 0.363; p = 0.003), and QoL (r = 0.481; p = 0.000). No correlations were found with age, time since diagnosis, cramps, or other mobility parameters. Conclusions Fatigue is a common symptom among individuals with ALS and may be present in all stages of the disease. This symptom was correlated with worse functioning, poorer QoL, greater pain intensity, disease severity, muscle weakness, and the female sex in individuals with ALS.

Resumo Antecedentes Esclerose lateral amiotrófica (ELA) é uma doença neurodegenerativa fatal que leva à fraqueza muscular e paralisia. Fadiga é um sintoma incapacitante, frequentemente relatado na ELA, mas permanece pouco investigado nessa população. Assim, uma investigação acurada deste sintoma e dos possíveis fatores associados é necessária para auxiliar em uma abordagem terapêutica adequada. Objetivo Investigar a presença de fadiga em indivíduos com ELA e possíveis fatores correlacionados a este sintoma. Métodos Participaram 65 indivíduos com ELA esporádica. Aspectos demográficos, clínicos e funcionais foram investigados. Foram utilizadas: Escala de Severidade de Fadiga (FSS, na sigla em inglês), Escala Funcional de ELA (ALSRFS-R, na sigla em inglês) e questionário de Qualidade de Vida (QV) (ALSAQ-40, na sigla em inglês). Análises descritivas e de correlação foram realizadas no programa SPSS para Windows versão 19.0 (IBM Corp., Armonk, NY, USA). Resultados Dos 65 indivíduos avaliados, 44,6% (n = 29) apresentaram fadiga pela FSS. A intensidade da fadiga foi 5,4 ± 1,2 e apenas 10,4% usavam medicamento específico para fadiga. Diferenças entre os grupos com e sem fadiga foram encontradas em relação ao sexo (p = 0,049), intensidade da dor (p = 0,026), funcionalidade (p = 0,004), gravidade da doença (p = 0,029) e QV (p = 0,000). A fadiga foi correlacionada com a intensidade da dor (r = 0,425; p = 0,001), força muscular (r = - 0,356; p = 0,004), funcionalidade (r = - 0,363; p = 0,003) e QV (r = 0,481; p = 0,000). Não foram encontradas correlações com idade, tempo de diagnóstico, cãibras ou outros parâmetros de mobilidade. Conclusões A fadiga é um sintoma comum entre os indivíduos com ELA e pode estar presente em todos os estágios da doença. Este sintoma estava correlacionado à pior funcionalidade, pior QV, gravidade, intensidade da dor, fraqueza muscular e sexo feminino em indivíduos com ELA.

Abstract The aim of this scoping review was to provide sufficient information about the effectiveness of ozone gas in virus inactivation of surfaces and objects under different environmental conditions. The review was performed according to the list of PRISMA SrC recommendations and the JBI Manual for Evidence Synthesis for Scoping Reviews. The review was registered in Open Science Framework (OSF). EMBASE (Ovid), Lilacs, LIVIVO, MEDLINE (PubMed), SciELO, Scopus and Web of Science were primary sources, and “gray literature” was searched in OpenGray and OpenThesis. A study was included if it reported primary data on the effect of ozone gas application for vehicle-borne and airborne virus inactivation. No language or publication date restriction was applied. The search was conduct on July 1, 2020. A total of 16,120 studies were screened, and after exclusion of noneligible studies, fifteen studies fulfilled all selection criteria. Application of ozone gas varied in terms of concentration, ozone exposure period and the devices used to generate ozone gas. Twelve studies showed positive results for inactivation of different virus types, including bacteriophages, SARS-CoV-2 surrogates and other vehicle-borne viruses. Most of the studies were classified as unclear regarding sponsorship status. Although most of the population has not yet been vaccinated against COVID-19, disinfection of environments, surfaces, and objects is an essential prevention strategy to control the spread of this disease. The results of this Scoping Review demonstrate that ozone gas is promising for viral disinfection of surfaces.

ABSTRACT Many students dislike Physical Education classes in Brazil because of content repetition, unsatisfactory curricular organization, among other factors. The purpose of this study is to assess the efficiency of a proposal for Physical Education classes, which includes contents of physical activities and the use of comic books application. This is a qualitative study, which comprises both bibliographic and field researches. Twelve classes were held to a group of eight graders from a public school in the city of Piracicaba/SP/Brazil. Questionnaires were used to evaluate the proposal for Physical Education classes. We found out that the use of comic books application is an effective teaching resource, as it reveals the students’ experiences, what they felt, and the mediation between their “rational” and “sensitive” knowledge about physical activities. There is evidence that our experience has provided participating students with: 1- Leisure education and health education, 2- Awakening to knowledge of the body culture of movement, 3- Access to some leisure contents, mainly those related to physical, sports and artistic ones, 4- The creation of comics by App Flaras.

RESUMEN A muchos estudiantes no les gustan las clases de Educación Física en Brasil debido a la repetición de contenidos, organización curricular insatisfactoria, entre otros factores. El propósito de este estudio es evaluar la eficiencia de una propuesta de clases de Educación Física, que incluye contenidos de actividades físicas y el uso de la aplicación de cómics. Se trata de un estudio cualitativo, que comprende tanto investigaciones bibliográficas como de campo. Se impartieron doce clases a un grupo de ocho alumnos de una escuela pública de la ciudad de Piracicaba / SP / Brasil. Se utilizaron cuestionarios para evaluar la propuesta de clases de Educación Física. Descubrimos que el uso de la aplicación de cómics es un recurso didáctico eficaz, ya que revela las experiencias de los estudiantes, lo que sentían y la mediación entre sus conocimientos "racionales" y "sensibles" sobre las actividades físicas. Existe evidencia de que nuestra experiencia ha proporcionado a los estudiantes: 1. Educación para el ocio participativa y educación para la salud, 2. Despertar al conocimiento de la cultura corporal del movimiento, 3. Acceso a algunos contenidos de ocio, principalmente los relacionados con los físicos, deportivos y artísticos, y 4. La creación de cómics por App Flaras.

ABSTRACT OBJECTIVE To analyze the impact of the covid-19 pandemic on the use of primary health care services to follow-up the child growth and development in Brazil. METHOD A total of 7.9 million consultations of children (0–2 years old) across Brazil between March 2017 and May 2020 were studied. Differences between medians were analyzed using non-parametric tests, the Global Moran Index (IGM) and the Local Indicators of Spatial Association. RESULTS During the initial period of the pandemic, the median number of consultations was significantly lower than the same period in previous years, reducing more than 50%. The drop in 2020, compared to 2019, ranged from 49% to 62.2% across all regions of the country, except the South. The percentage reduction registered in 2019–2020 showed significant spatial autocorrelation (IGM = 0.20; p = 0.04), with the presence of low-low (states with reduction between 29% and 51%) and high-high (states with reduction between 55% and 69%) spatial clusters. CONCLUSION The covid-19 pandemic impacted the follow-up of child growth and development in primary health care services in Brazil, with a geographically uneven reduction.

Abstract Aim: The influence of sleep on the adaptability and relearning rate during learning of complex motor skills is still unknown, limiting the comprehension of the sleep role in motor memory consolidation. Thus, we aimed to investigate the nocturnal sleep influence on retention, adaptability, and relearning rate of the dart-throwing task. Methods: Sixty healthy adults were divided into two groups: SLEEP and WAKE. Both groups practiced an under-arm dart-throwing task. However, WAKE practiced in the morning and performed a retention phase in the evening, and SLEEP practiced in the evening and performed a retention phase in the morning of the next day. The practice and retention phases were separated by 12 h in both groups. There were analyses regarding retention (retention test), adaptability (delayed transfer test), and relearning rate (savings). Results: Both groups improved their performance across the acquisition phase and maintained it in the retention test. The groups did not demonstrate adaptability and did not demonstrate a significant difference in relearning rate. Conclusion: We conclude that nocturnal sleep did not modulate the consolidation of motor memories related to ballistic discrete motor skills.

Abstract Carbonaceous porous materials are strong candidates for producing low-cost, lightweight, and sustainable electromagnetic (EM) absorbing materials. This work investigates the production of radar-absorbing materials (RAM) by a simple method. Sustainable carbon xerogel (CX) was synthesized from tannin, a biosourced molecule. CX and commercial carbon nanotube (CNT) were embedded in a silicone matrix at proportions of 10 and 15 wt.% of CX and 0.1 wt.% of CNT to produce flexible composites. The morphology and structure of the carbonaceous materials were evaluated by field-emission scanning electron microscopy (FEG-SEM), Raman spectroscopy, X-ray diffraction (XRD), textural properties by N2 adsorption-desorption isotherms, and mercury porosimetry. The electromagnetic characterization of the composites was analyzed by a vector network analyzer (VNA) in the Ku-band. The results demonstrated that an increased concentration of CX in the composite improved reflection loss reaching -43.19 dB at 13.79 GHz.

RESUMO O comprimento corporal é um importante parâmetro em estudos morfológicos, ecológicos e comportamentais de uma espécie e contribui para o entendimento da condição corporal de um indivíduo. Este parâmetro é essencial para estratégias de conservação e manejo, informando estudos que avaliam taxas de crescimento, maturidade física e classificação dos indivíduos em grupos de idade, promovendo uma melhor precisão aos parâmetros biológicos de uma espécie. O objetivo desse trabalho foi identificar preditores de comprimento corporal para o peixe-boi da Amazônia (Trichechus inunguis) utilizando caracteres métricos de material osteológico. Onze medidas lineares do crânio, mandíbula, escápula e úmero foram coletadas de 41 esqueletos de peixe-boi da Amazônia de diferentes classes de idade (filhote, juvenil e adulto). Os dados foram analisados por regressão linear simples. O comprimento côndilobasal foi o melhor preditor de comprimento corporal para a espécie (R = 0,943), entretanto, todos os ossos avaliados mostraram pelo menos um caractere com capacidade de predizer o comprimento corporal (R2 > 0,9). Os resultados deste estudo são úteis para inferir o comprimento corporal de peixes-boi da Amazônia a partir de ossos depositados em museus e coleções biológicas, expandindo o potencial informativo destes materiais.

ABSTRACT Body length is an important parameter in morphological, ecological and behavioral studies of a species and contributes to the understanding of the body condition of individuals. This parameter is essential for conservation and management strategies by informing studies evaluating growth rates, physical maturity and classification of individuals into age groups, promoting better accuracy for the biological parameters of the species. The aim of this study was to identify predictors of body length for Amazonian manatees (Trichechus inunguis) using metric characters of osteological materials. Eleven linear measurements of skull, jaw, scapulae and humeri were collected from 41 Amazonian manatee skeletons of different age classes (calf, juvenile and adult). Data were analyzed by simple linear regression. The condylobasal length was the best predictor of body length for the species (R = 0.943), however, all bones evaluated showed at least one measurement with the capacity to predict body size (R2 > 0.9). Results of this study are useful for inferring body length of Amazonian manatees using bones deposited in museums and biological collections, expanding the informative potential of these materials.

Resumo Qualea grandiflora é uma espécie típica da fisionomia cerradão, de importância ecológica, florística e medicinal. No entanto, são pouco os estudos no que se refere a sua fenologia. Diante do exposto, objetivou-se verificar a sazonalidade e influência das variáveis climáticas nos eventos reprodutivos de Qualea grandiflora em cerradão. Marcaram-se 15 indivíduos que foram visitados mensalmente entre julho de 2016 e junho de 2018 para registrar os eventos: botões florais, antese, frutos imaturos e maduros. A intensidade de Fournier e sincronia foram correlacionadas com a precipitação, temperatura máxima, média e mínima através da correlação de Spearman, e a sazonalidade por meio da estatística circular. A espécie produziu botões e flores durante a estação chuvosa, o que resultou em correlação positiva com a precipitação. A formação de frutos ocorreu tanto na época chuvosa quanto na seca, já a maturação dos frutos ocorreu na estação seca. O evento de frutos imaturos foi o único não sazonal devido a sua duração. Os eventos reprodutivos de Qualea grandiflora se correlacionaram com a temperatura e a precipitação, de modo que a espécie utiliza essa influência para potencializar suas chances de reprodução.

Abstract Qualea grandiflora is a typical species of the ‘Cerradão’ physiognomy, of ecological, floristic and medicinal importance. However, there are few studies regarding to its phenology. In view of the above, the objective was to verify the seasonality and the influence of the climatic variables on the reproductive events of Qualea grandiflora in ‘Cerradão’. Fifteen (15) individuals were visited and visited monthly between July 2016 and June 2018 to record the events: flower buds, anthesis, immature and ripe fruits. Fournier's intensity and synchrony were correlated with precipitation, maximum, average and minimum temperature through the Spearman's correlation, and seasonality using circular statistics. The species itself produced buds and flowers during the rainy season, which resulted in a positive correlation with precipitation. The fruit formation occurred both in the rainy and dry season, whereas the fruit ripening occurred in the dry season. The immature fruit event was the only non-seasonal event due to its duration. The reproductive events of Qualea grandiflora correlated with temperature and precipitation, so the species uses this influence to enhance its chances of reproduction.

Resumo A manga (Mangifera indica L.) tem grande importância socioeconômica no Brasil, porém sua produção é afetada pela antracnose. Filmes de quitosana têm demonstrado potencial no controle desta doença. Neste estudo, avaliou-se a associação de quitosana com compostos fenólicos e extratos no desenvolvimento de Colletotrichum tropicale. Compostos fenólicos e extratos da casca da manga foram incorporados às soluções de quitosana a 2,0% e testados in vitro. No experimento in vivo, após a inoculação do patógeno e a aplicação dos tratamentos, os frutos foram avaliados quanto à incidência e à severidade da antracnose. As testemunhas consistiram na aplicação de água ou no meio de cultura puro e do fungicida imazalil (2,0 mL .L-1). O delineamento experimental foi inteiramente casualizado, e os dados foram submetidos à análise de variância. No teste in vitro e na avaliação da intensidade de doença, as médias foram comparadas pelos testes de Scott-Knott e Tukey (p <0,05), respectivamente. As testemunhas foram comparadas aos demais tratamentos pelo teste de Dunnett (p <0,05). Inibição total do crescimento, produção de conídios e germinação de C. tropicale foram verificadas com incorporação à quitosana dos ácidos cítrico, pirocatecoico e transcinâmico, não havendo diferença significativa entre eles e o fungicida. Foi verificada baixa incidência e severidade de antracnose nas mangas tratadas com quitosana, combinada com compostos fenólicos.

Abstract Mango (Mangifera indica L.) has great socioeconomic importance to Brazil, but its production is affected by anthracnose. Chitosan films have shown potential in controlling this disease. In this study, the effect of the association of chitosan with phenolic compounds and extracts on the Colletotrichum tropicaledevelopment was evaluated. Phenolic compounds and extracts from mango peel were incorporated into 2.0% chitosan solutions and tested in vitro. In the in vivo experiment, after pathogen inoculation and application of treatments, fruits were evaluated for anthracnose incidence and severity. Controls consisted of the application of water or pure culture medium and fungicide imazalil. The experimental design was completely randomized and data were submitted to analysis of variance. In the in vitro test and in the assessment of disease intensity, means were compared using the Scott-Knott and Tukey tests (p <0.05), respectively. Controls were compared to the other treatments using the Dunnett test (p <0.05). Total growth inhibition, conidia production and C. tropicale germination were verified with the incorporation of citric, pyrocatecoic and transcinamic acids to chitosan, with no significant difference between them and the fungicide. Low anthracnose incidence and severity was observed in mangoes treated with chitosan combined with phenolic compounds.

Resumo Objetivo Investigar os efeitos da abreviação do jejum pré-operatório, por meio de solução enriquecida comcarboidrato e proteína, na incidência de náuseas e vômitos no pós-operatório (NVPO) em cirurgias ginecológicas, população naturalmente de risco para esses episódios desagradáveis. Métodos O presente estudo prospectivo randomizado duplo-cego foi realizado no Hospital e Maternidade Municipal Dr. Odelmo Leão Carneiro (HMMOLC), em Uberlândia, estado de Minas Gerais, Brasil, emparceria como Departamento de Ginecologia da Universidade Federal de São Paulo (UNIFESP), aprovado pelo Comitê de Ética em Pesquisa da UNIFESP, pela diretoria do HMMOLC, registrado na Plataforma Brasil e na plataforma de Registro Brasileiro de Ensaios Clínicos. Após assinatura do termo de consentimento, foram randomizadas 80 mulheres que se submeteram à cirurgia ginecológica, de janeiro a julho de 2016, em 2 grupos: grupo controle (n = 42) e grupo suco (n = 38) que receberam, respectivamente, 200 ml de solução inerte ou 200ml de líquido contendo carboidrato e proteína, 4 horas pré-cirurgia. Foram estudadas incidência, frequência e intensidade de NVPO por meio da Escala Visual Analógica (EVA), com análise estatística realizada pelo programa IBM SPSS Statistics for Windows, Versão 20.0 (IBM Corp, Armonk, NY, EUA). Resultados A incidência de náuseas e vômitos foi mais baixa que a esperada na literatura para essa população, com 18,9% (14/74) para o grupo controle e 10,8% (8/74) para o grupo suco, respectivamente, sem diferença estatisticamente significante entre os grupos. Conclusão A incidência de náuseas e vômitos foi mais baixa do que na literatura; entretanto, não se pode afirmar que foi devido à abreviação de jejum. Essa medida pode trazer maior conforto com a possibilidade de prevenção de NVPO em pacientes de risco para esses eventos.

Abstract Objective To investigate the effects of preoperative fasting abbreviation with a carbohydrate and protein-enriched solution, on postoperative nausea and vomiting (PONV) incidence in gynecological surgery patients, a population naturally at risk for such unpleasant episodes. Methods The present prospective double-blind randomized study was performed at The Hospital Municipal e Maternidade Dr. Odelmo Leão Carneiro (HMMOLC, in the Portuguese acronym), in Uberlândia, state of Minas Gerais, Brazil, in partnership with the Gynecology Department of the Universidade Federal de São Paulo (UNIFESP), approved by the Human Research EthicsCommittee ofUNIFESP and theboard ofHMMOLC, and included in the Brazil Platform and in the Brazilian Clinical Trial Registry. After signing the consent form, 80 women, who were submitted to gynecological surgery in the period from January to June 2016,were randomized into 2 groups: control group (n= 42) and juice group (n= 38). They received, respectively, 200mL of inert solution or liquid enriched with carbohydrate and protein 4 hours presurgery. The incidence, frequency and intensity of PONV were studied using the Visual Analogue Scale (VAS), with statistical analysis performed by the software IBM SPSS Statistics for Windows, Version 20.0 (IBM Corp, Armonk, NY, USA). Results The incidence of nausea and vomiting was lower than in the literature, to this population, with 18.9% (14/74) for the control group and 10.8% (8/74) for the juice group, respectively, with no statistically significant difference between the groups. Conclusion The incidence of nausea and vomiting was lower than in the literature, but it cannot be said that this is due to the abbreviation of fasting. It can provide greater comfort, with the possibility of PONV prevention in patients at risk for these episodes.
